Catalyst 6509 IOS code versions

[glen.grant]

  Is Cisco moving away from the 12.2 SX  trains and on to  15.X trains only ?  Currently they have the 12.2 SXJ train , will there be any other 12.2 codes after this? Will they move to like SXK after this or should we move to the 15.X trains even though it doesn't really offer us anything we need .  Will all fixes only be on the 15.X train in the future . I see that the 12.2 SXJ is like EOL in Sept 2015 , is this the last version in the 12.2 train ?  Trying to determine upgrade path for our 6500's which currently run 12.2 SXI train .

As far as I remember Cisco never produced any IOS after the SXJ train. They moved to 15SY after that.
